Hi, after a bit of thought this is how it happened from what i learnt till now.
select max px - mins px from t where sym=`aapl


as it goes from Right to Left, steps indicated with numbers:
1. Filtering happens on the table where aapl is selected
2. minimum value of price are calculated
3. minimum values of price are deducted from price
4. maximum of differences from step (3) is selected.


Nice but interesting approach.

Excellent series, Jeffery. As a new user setting up a server, I'd love to see best practice to access the server to edit/change functions while still maintaining a local environment.
